[QUOTE="CurtisF, post: 249999, member: 829"] I dyno'ed right before Truck Fest in August. Made right at 408 hp on the rollers with some uber-conservative timing. Timing was pulled back so far that I hit a point where increasing PW was netting zero increase in HP, but just pouring out black smoke. So I re-addressed the timing, and bumped it up since then. Time slip at Bandimere suggests around 425-430 hp (14.4 @ 92 mph on a 8000 lbs lifted truck). Since Truck Fest I've addressed various tuning strategies and many tweaks, but never have I increased the fuel pulsewidth above what I used to make my last run. However, ICP and timing changes obviously have had an effect on overall power, so I'm not really sure right now if I'm higher or lower. Other than that, it runs fine. I'm still dialing in the tuning, although it's been slow lately, and I only get to it every now and then. It runs fine overall, except some idle quality issues. Other than that, EGT's are low, there's very little smoke, and it runs like a beast. Even cold starts in single digit temps aren't too bad for such large nozzles. Used to be worse, but I've significantly reduced it over the past few weeks. [/QUOTE]
